It calls it cooling because that is what the system is designed to do and does. Obviously they have a heating system for the cabin.

As far as why they don't have a battery heater, you will have to check with the engineers to see why they determined it was not necessary for the use case. EV's also don't have an ICE.

Battery heating is not so crucial for plug-ins since you still have ICE, there's no need to supercharge, etc etc.

It looks like BMW uses cabin air to cool the batteries; other plug-ins like Toyota Prime uses the same. It's fine, in general, since the battery is essentially supplemental and its load can be managed more freely unlike pure EVs where it plays the primary role.

Toyota is fan cool, right? Batter is under seat, there are vent above door sill.

Per the documents at the top of the forum, the hVB are cooled by refrigerant (see page 24).

You'd have to replace the transmission where the electric motor lives. So that's probably a no.

I mean, it seems like a wasted opportunity to upgrade from 45e power to 50e power.
